Question: A bat locates insects by emitting ultrasonic "chirps" and then listening for echoes. The lowest-frequency chirp of a big brown bat is 26kHz. How fast would the bat have to fly for you to just barely be able to hear the chirp at 20kHz? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
